to provide a corn harvesting machine which in-* I eludes rotors forpicking up corn that is down and resetting the same in proper positionfor gathering effect by the picker.

Other objects and advantages of the invention.

will become apparent to the reader of the following specification. 1 In:the drawings:

Figure 1 represents a top plan'viewpf'a por-- tion\ of a picker machine.

Figure 2 is a side elevational view partly in g 6, 7 and 8. Each'ofthese reel types 25 which can 20 section to show the gears. 5

Figure 3 is a top plan view of .the auxiliary picker cylinders Figure 4is an enlarged cross section on the line 44 of Figure 3.

Figure 5 is an enlarged sectional view on the line 5--5 of Figure 2.

Figure 6 is an enlarged top plan vi'e'wof the reel type auxiliarypicker.

Figure 7 is an enlarged sectional view on a'line 1-1 of Figure 6.

Figure 8 is an enlarged cross sectional view on a line .88 of Figure 6.

Referringwto the drawings,-wherein like numerals designate like parts,it can be seen in- Figure 1, that numeral 5 generally. refers-toapicking machine of the'tworow type which in general respects isconventional, the same consisting of t lines'consis mg of convergingteeth I on'endless chains (not shown) such as are found 'in conventionalcorn harvesting machines. Y

In carrying out the present invention, each of the side shields 6 is cutaway as at 8 to accom- 45 modate the corresponding auxiliarypicker'cylinder which is generally referred to by numeral 9. Each ofthese cylindersc'onsists of the drum III having a "longitudinallyextending spiral rib n disposed thereon and suitably secilred thereto-50 and driven into this drum ill at longitudinally spaced intervals arecircumferential rows of studs l2, each having a threaded portion fordisposition into the drum and a polygonal shaped outwardly projectinghead.

5 Each of these drums I0 is mounted on a shaft l3 which at its upper endhas a bevel gear l4.

One of these shafts l3. has a sprocket wheel ii at its upper end whichis driven by a sprocket no chain 16 extending from the sprocket wheelI'I bevelled gears M on the shaft l3.

side shields 66 and the two picker 20 is trained and this chain 20 alsoextends over the sprocket wheel H on the power take-off shaft s 22(seeFig. 1). One drum ill drives the other through the agency of a shaft23 which at its ends is equipped with bevelled gears 24- 24 for meshwith the It can be seen, that rotation of-the drums 9 will result in thepicking of the ears of corn from thecorn' stalks. Obviously, the spiralsserve to feed the ears upwardly. Obviously, the studs 12 serve to catchthe ears to carry the sanieinl5 wardly where they are moved upwardly bythe spiral I l A reel type of auxiliary means -is generally referredtoby numeral 25 and is shown in Figures a stop collar 28 on the shaft Mabears.

Circumscribing the cylinder 26 and slightly spaced therefrom are thespiral bands 29 which, extend longitudinally of the cylinder 26 andjareconnected at their ends to the disks 21, these 30 disks preferablyhaving skirt portions 30 which overlap the ends of the-cylinder 26..

Thus it can be seenthat down corn in settling on the stationary drum 26"is fed upwardly of the drum by the spirals 29.

While the foregoing specification sets forth the invention in specificterms, it is to'beunderstood that numerous changesin the shape,-sizeand'materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter. i

' Having described the invention, what is claimed as new isi l l 1. In acorn picking machine, picking means,

a side shield and an auxiliary corn catching rotor.

mounted on the shield adjacent the picker means,

said roll being provided with aspiral rib extending longitudinallythereof and outwardly pro-- jecting studs on the roll.

2. In a corn picking machine, picking means, a side shield, anauxiliarycorn catching drum rotatably mounted on the shield andadjacent'the picker means, said 'tlrum being provided with a spiral ribextending longitudinally thereon, and 55 spaced studs projecting fromthe periphery of the drumand arranged in longitudinal andcircumierential rows.
